HI87314

Description

The HI87314 is a durable, portable EC and resistivity meter designed for use in applications such as manufacturing and quality control. It is supplied with a four-ring conductivity probe to allow for four ranges of EC measurement and one range of resistivity measurement The temperature compensation coefficient (β) is adjustable from 0 to 2.5%/°C for conductivity and from 2 to 7%/°C for resistivity. All readings are automatically adjusted for temperature, assuring users of consistent and accurate measurements.

•  Adjustable temperature coefficient (β)
•  EC and Resistivity Portable Meter
•  Four-ring probe

The portable HI87314 EC and resistivity meter is suitable for use in a wide range of applications. It offers four conductivity measurement ranges from 0.0 µS/cm to 199.9 mS/cm with ±1% FS accuracy as well as a resistivity measurement range from 0 to 19.90 MΩ•cm with ±2% FS accuracy. The HI76302W four-ring conductivity probe that is supplied with the meter allows for a wide range of measurements with a single sensor. The four-ring technology also eliminates the polarization effect that is common with standard two pole versions. The HI87314 offers Automatic Temperature Compensation (ATC) from 0 to 50°C (32 to 122°F) and an adjustable temperature coefficient (β).

  Features/Benefits:
Automatic Temperature Compensation
•  Since temperature has such a dramatic effect on conductivity and resistivity readings, having a meter that offers temperature compensated readings is invaluable.
•  Both probes that are supplied with the HI87314 feature built-in temperature sensors that automatically account for the effects of temperature on a sample’s
reading in the range of 0 to 50°C (32 to 122°F).

  Adjustable Temperature Coefficient
•  As the temperature of a solution increases or decreases, the conductance becomes higher or lower, respectively.
•  The temperature compensation coefficient, also known as β, is the factor that adjusts for the temperature of a solution to ensure an accurate reading is achieved.
•  The HI87314 allows for an adjustable β to be set from 0 to 2.5%/°C for conductivity and from 2 to 7%/°C for resistivity; this factor corrects readings by the set
set percentage for each degree Celsius change in the sample.

  Four EC Measurement Ranges
•  HI87314 offers four conductivity measurement ranges.
•  Each range has a dedicated button on the face of the meter, allowing users to easily switch between ranges when necessary.
•  The meter is programmed to let the user know when their current reading is out of range, and a new range should then be selected.

  Four-Ring EC Probe
•  The HI76302W four-ring probe that comes with the HI87314 offers a versatile and accurate solution for conductivity readings.
•  Four-ring technology allows for a larger range of measurement within a single probe, whereas two probe technology is somewhat limited in the range in which it can measure.
•  The probe comes with a protective PVC sleeve that assures durability when taking measurements outdoors, and a built-in temperature sensor to allow for automatic
temperature compensation.

  One-point Calibration
•  The HI87314 can be calibrated at one point in a standard conductivity solution.
•  The calibration knob located in the battery compartment of the meter is easily adjusted to the correct calibration standard.

  Resistivity Probe
•  The HI3316D resistivity probe is also included with the HI87314 portable meter.
•  Specially designed to measure resistivity, the easy to maintain probe features a built-in temperature sensor for accurately compensated resistivity readings.
